I have to make them fresh to order so they last as long as possible for you :) if you keep them refrigerated they can last a couple weeks versus on the counter you'll have a few days with it before it starts to go bad... just depends on how quick you'll be using the lotion ;) there are NO fragrances so it will not irritate you at all (the burn question was a joke because I'm a smartass if you haven't figured that out yet)
